To all whom, it may concern.'

Be it lstnov'vi'i that uduimen Tessinne citizen of the FrenchfRepubl-ic,residing in the city of Philadelphie, coun-ty 'of Philetional view tekentransversely reuniera embodying delphia, and Stute invented certain`lniprovernents in Filin- Guiding Mechanismof which the 'following is especification.

My improvements 'rel-ete' more particularly to ineens tor-guiding thel'rn's-v for moving picture lmachines in the operetions of passing themthrough perioreting in achines, cameras end projecting machines, and myleading object is to provide simple, convenient and eilicient guidingmechanism which cnn be opened ifor. the-ready insertion and Withdrawalof and access to the `film sections in the operation of'iieeding them.

rlhe cherecteristic dentures of my provements'are fully disclosed in theiollowing description sind' fthe accompanying drawings in illustrationthereof.

rllhe invention, es illustrated in Figs. l to 6 inclusive, is embodiedin a performing `man chine comprising the hed l having the reels 2 and 2journeled et its opposite ends, the longitudinal plete 3 over which thetilni is fed, the rollers d and 4.- lor passing the lilin over theplete. and the perfoi'eting mechenisin under which the iilin is drawn.Plates 6 and Y are movably supported on the plates Set theopposite'sides oi? the central section 3" end 'ere provided with guidesn and 7 hevine vertical legs inovnlole internliy in the pere-livellongitudinal channels 3" Spceicetion ci Letters'etnt.

Levers 8 are fule'rumed on 'studs 9,set in the underside of the plate 3, and are connected with the linksl() by studs 11 which pass through the slots 3a into the respectivepletee ,6 end i', e spring l0J connected- With e lever and -a linknormally holding A link 12 is pivotell'y connected by studs .i3 with therespective plates Send Y on the opposite side of the fper'icnratingdevice 5 from the levers e. lm protector comprising a cover or door Misconnected to the plate 3 by the `hii'iges'l and is provided with erearwardly projecting lug or' cuni 16 which engages the ce'rn l? on theleed l, `the cern l'engaging the shoulder G of the plete 6. The doorli's provided With-the latch 18 iulorurned 'thereon and adapted to loeheld by the spring 19 in lengeigelfnent With the hasp 20, whereby thedoor is held closed over the roller i and the film thereon. When thelatch 18 is disengaged from the hasp 20 and the .parts in thev the door14 is opened, the cani 16 thereon' 'rocksthe cern 17 and moves the plete6 in the direction of the arrow thereon, this plete acting through thestuds ll lixed thereto to move the levers 8 toward positions et rightangles' thereto so es to spread the plates 6 and *.7 with the guides 6and 7 thereon. 'llhe filn'i, having heen inserted, removed yorexainiiied, es circumstances may require, upon closing the door Ll thespring l0 acts to restore the mechanism to its normal position, in whichthe guides 6', and 7 occupy their closest relation, ing the edges of thefilm and guiding it with accuracy es it is carried through the machinebetween the reels 2 and 2', over the rollers d and li and under theperfor-ating device The invention, in the form illustrated in Figs. 7 tol0 inclusive, comprises the box 20 containing the diaphragm 2l providedWith thelight aperture 22 and the door 23 having the hinges Levers 25ere journeled on studs 26 set in the diaphragm 2l and are `connected bythe studs 27 with the parallel guides 28 end 28 on the opposite side ofthe diaphragm from the levers, the studs 27 heing niovehle in the slots29 of ehe diaphragm. These guides are held in their closestreletion, inposition 'for guiding the lilni across the eperture 22, by the spring 30connecte-l n.ehregin 2l and one o the levers with `25. f Theguides,=wliich" are movamelaterally and longitudinally in the channels21 ofthe! diaphragm '21, are s read forzthe sertion or removal of the yby means of va cam 31 fixed to v'one of them and the `complementary cam32 iXed to thevv door* 23S" When the door is swung out .on its hinge 24-infthe"operation-efl opening it, the ca1ir32y thereon` engages the cam31 on thefguide 28= and forces it downwardly, thereby moving the leverstoward'positions at'right angles thereto, whereby "the lguides arespread.

' When the door is closed, the spring 30 moves the guides28 and 28together in'to position or engaging the edges of the film fedA over vthe sprocket 33 and drawn between the dia- "otally connecte rocking saidlevers to increase the dlstance,
